Why Choose the IMO AA1/CP-1A Inductive Proximity Switch?
The IMO AA1/CP-1A is a super-miniature 3 mm diameter shielded inductive proximity switch designed for precise non-contact detection of metallic objects in compact industrial automation equipment. Part of the IMO Miniature Inductive AA Series, its exceptionally small cylindrical housing makes it particularly suitable for machinery where installation space is restricted.
The AA1/CP-1A provides a DC PNP normally closed (NC) output with a nominal sensing distance of 0.6 mm. Its shielded construction allows flush installation into surrounding metal, while a switching frequency of up to 3 kHz supports rapid detection of small moving components in high-speed automation applications.
Operating from a 10 to 30 V DC supply, the sensor features short-circuit, reverse-polarity and inductive-load protection together with a yellow LED output indicator. Its AISI 303 stainless steel housing, IP67 protection and integral 2 m PUR cable provide a robust pre-wired sensing solution for industrial machinery and precision automation systems.

The IMO AA1/CP-1A generates an electromagnetic sensing field at its active face. When a suitable metallic target enters this field, the sensor detects the resulting change and switches its PNP normally closed output. Because detection takes place without physical contact, the sensor avoids the mechanical wear associated with conventional limit switches and is well suited to repetitive machine cycles.
Its Ø3 mm body, 0.6 mm nominal sensing range and 3 kHz switching capability make the AA1/CP-1A particularly useful for detecting small or rapidly moving metal components. Combined with its stainless steel housing, IP67 protection, electrical protection functions and PUR cable, it provides a compact sensing solution for precision industrial automation.
